Plastic is one of the most common artificial materials used in our daily lives.

But did you know that plastic also plays an important role in the medical industry?
5
Plastic has caused significant changes in the medical industry by reducing the risk of infection.

Before disposable plastic products existed, hospitals used to boil medical tools to sanitize them.

Although this method worked, there was a danger of infection if the tools were not properly sanitized.

However, disposable products have solved this problem.

Another medical use of plastic is to make artificial joints.
10
Artificial hips and knees are needed by many older people so that they can continue to walk.
11
In the past, most artificial joints were made of metal.

But plastic has the advantages of weighing less and being able to be easily formed into any shape.

Today, many joints are made from a combination of metal and plastic parts.

Finally, how's your eyesight?

If you wear glasses or contact lenses, you can thank plastic for giving you good eyesight.

Instead, plastic is used.

Plastic eyeglass lenses are lighter, thinner, less likely to break, and harder to scratch.

And contact lenses are made of plastic too.

This makes them more comfortable than those that were made of glass.

While plastic causes some environmental problems, it also brings us many benefits.

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
